JOHN MCGLADE, OF NEWTON, MISSISSIPPI.

LADDER.

Application filed July 19, 1909. Serial No. 508,383.

To all whom 'it 'may concern.' I

Be it known that I, JOHN MCGLA'DE, a

citizen of the United States, residing at Newton, in the county of Newton and State of Mississippi, have invented a new .and

useful Ladder, of which the following is a. specification.

This invention has4 reference to ladders and is designed to supply a. ladder which is adapted to be carried on box cars, -and further tosupply a hand hold for box, fiat and gondola cars.

It contemplates the construction of a ladl der and hold of this type and character which will eliminate the greatloss of life now ycaused by ladders breaking loose, and by the inefficiency of such'structures, and at the same time contemplates increasing the strength and durability of car ladders.

With the above and other ends in view the invention consist-s in the construction, combination and arrangement of parts all as hereinafter fully described, specifically claimed and illustrated in the accompanying drawings, wherein Figure 1 is an elevation of one of my improved ladders secured to a box car. Fig.- 2 is a longitudinal section taken through the angle iron and showing the method 'of securing the same to the car. Fig. 3 is a t transverse section showing the method of securing the rounds or holds to the angle iron. Fig. 4. is a plan of the hand hold and the to of the car. Fig. 5 is a .fragmental side e eva-tion of one of the angle irons; a portion of the car, and the corner plate thereof, being shown in section.

My invent-ion involves in its-organization, a pair of angle irons 1, secured to the side ofthe car by the U bolts 2, having their extremities secured in the openings 3, piercing at regular intervals, the base portion of the angle irons. The means shown whereby the said bolts are secured to the angle irons comprises nuts 4 threaded upon the bolts, the extremities thereof may however, be swaged or welded to the angle irons or in fact` secured by any of the many practical and suitable ways known to railroadA lne- `'chanics The angle iro-n adjacent the car corner is recessed in its under face for the reception` vof the corner plate 18, thus'pern'litting. the iron to rest flush with the Wall of the carl Occurimy at re )fularl intervals a-lon the e outstanding flanges of the ,angle irons, are the orifices (3 1n which are carrled the rungs or holds 7. These holds comprise vtransverse bars each one of which is bentinwardly at its extremities forming hooks 5), which are received in said orifices 6, and secured therein by any suitable means, the bars being shown in the drawings as riveted at 3.

In order to provide a hold uponthe roof of the car, there is carried thereon adjoining the ladder, a pair of stub angle bars 10, secured to the roof by U bolts similar to those used to secure the ladder, the stubbars carrying a hold 17, of a construction identical with` that of the rungs or holds 7 of the ladder.

From the foregoing it can readily be seen that the. U bolts securing this ladder to the side of the car form a firm and reliable Specification of Letters Patent. Patented Mar. 22, 19M).

fastening means whereby the danger of the ladder being disengaged from the car is eliminated and the strength thereofv is increased. It willV further be noticed that should any of the rungs become broken 0r worn they may be replaced without any interference with the angle bars.

I have used the' term angle'irons throughout the foregoing description, and in the following claims, in its'commonly accepted sense, to denote vthe shape of the members l, and not as a phrase of limitation, to indicate that the members 1 must of necessity be fashioned from iron.

Having thus fully described my inven-` tion what I claim. as new and desire to secure by Letters Iatent'is:4

l. A ladder comprising rails fashioned fronranglc members; means for detachably securing one flange of each angle member to a structure; and rungs connecting the otherf flanges of the angle members.

A ladder comprising ra'ils fashioned from angle members; support-engaging bolts vengaging' one flange of each angle member; and rungs connecting thejother flanges of the angle members.

3. A ladder comprising raiis fashioned from angle members; support-'engaging bolts engaging one flange of each angle member; and rungs terminally hooked to engage the other flanges of the angle members.

4. In aladder structure for cars, a pair of angle members vertically secured to the side 319 of the car; a air of angle members secured to the top of t e car adjacent the ends of the first pair; and rungs connecting the angle members of each palr. 'I

5. A ladder adapted to be mounted upon a car provided with a corner plate, the lad der comprising rails fashioned from angle members, one of which is recessed for the reception of the ccrner plates; and rungs uniting the rails. y

6. A ladder ada tedl to be mounted u on a car provided with) a corner plate, the la der comprising rails, one of which is recessed for the reception of the corner plate; and rungs uniting the rails.

7. A ladder of the class described, comprising a pair of angularl-y formed vertically extending rails, means for detachably securing said rails to the side of a car, and run s carried in the outwardly projecting ange portionof said rails.

8. A ladder of the class described, comprising a pair of vertically extending angle irons, means for detachably securing one arm of said angle irons to the side of a car,

Vand rungs carried at regular intervals bythe other of said arms.

9. In a ladder of the class described the combination With a support, of a'pair of vertically extending angle irons, U bolts passing through the support and engaging the base arm of said angle irons at regular intervals, and run-gs held in spaced parallel relation on the other of said arms.

10. In a device of the class described, a

su ort' a' air of angle irons mounted ver- `receive t-he hooks.

l l1. In a ladder gf the, class described, the combinationI with a ear, of a pair of vertically extending an le irons, U-bolts passing through one ywal of the car and securingl the base arms of said angle irons to said Wa l of the car; and a similar ladder secured to the top of the car in a like manner to form a hold. y 12. vIn a ladder of the class described, a pair of vertically extending' angle irons, the under face of one of said angle irons being recessed for the reception of the corner plate of the car, and rungs uniting the angle irons. In testimony that I claim the .foregoing as my own, I have hereto affixed my signature in the presence oi' two Witnesses. JNO. MCGLADE, Witnesses J. H. CHARLWoon',
